CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 USC §119 of Chinese PatentApplication having Serial No. 200510030341.4 filed on Oct. 10, 2005,which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the present invention generally relate to a type of soilauger assembly. More particularly, embodiments of the present inventionrelate to a soil auger assembly which can be used to shrink and loosenup various types of materials, to drill holes in soil to any depth, canbe disassembled and stored and to take samples in different depths ofsoil.

2. Description of the Related Art

The soil auger disclosed in Soviet Union Standard SU 1076808 (1984)includes an extension rod equipped with a handle and a hollow tubehaving a longitudinal groove. The tube is formed in a spiral shape.There are scales on the extension rod which can be used to indicatedepth. The length of the handle and the extension rod can be adjustedvia a stopper. There is a projection at the bottom of the extension rod,where a flat helical auger will be connected. The blade of the auger isopen. A fixation element is installed at the bottom of the extensionrod, and the auger is firmly installed on the fixation element. Thisdesign has several disadvantages. First, the handle and the extensionrod are connected together. Second, the size of the entire tool is verylarge, making it difficult to carry around. Third, although the lengthof the handle and the extension rod is adjustable, the adjustment islimited. Fourth, the drill is unable to handle the situation when thesoil to be drilled is too deep and exceeds the adjustable length of thehandle and the extension rod.

There is a need, therefore, for a soil auger assembly that is easy tous, can be disassembled and stored, can drill holes to any depth andtake samples at different depths of soil.

SUMMARY OF THE INVENTION

In one or more embodiments, the soil auger assembly can be disassembledand can reach the soil at any depth.

In one or more embodiments the soil auger assembly includes augers,cutting blades, handles, extension rods, working shafts, and beveledtips. The auger and cutting blade can be wound spirally on the workingshaft. The extension rod can be integrated with the handle. The soilauger assembly includes at least one connection rod which can bearranged between the extension rod and the working shaft. The soil augerassembly includes at least one connection rod which can be connected viaa slotted screw thread.

In one or more embodiments, the connection rod can be connected betweenthe extension rod and the working shaft via a slotted screw thread. Inthis way, the soil auger assembly can be disassembled when not in use sothat the soil auger assembly can be transported and stored easily. Ifnecessary to drill relatively deep soil, several connection rods can beconnected to increase the length of the soil auger assembly toaccommodate different depths. This drill can be used very easily. In oneor more embodiments, the soil auger assembly can be disassembled and candrill soil at any depth.

DETAILED DESCRIPTION

A detailed description will now be provided. Each of the appended claimsdefines a separate invention, which for infringement purposes isrecognized as including equivalents to the various elements orlimitations specified in the claims. Depending on the context, allreferences below to the “invention” may in some cases refer to certainspecific embodiments only. In other cases it will be recognized thatreferences to the “invention” will refer to subject matter recited inone or more, but not necessarily all, of the claims. Each of theinventions will now be described in greater detail below, includingspecific embodiments, versions and examples, but the inventions are notlimited to these embodiments, versions or examples, which are includedto enable a person having ordinary skill in the art to make and use theinventions, when the information in this patent is combined withavailable information and technology.

FIG. 1 depicts a partial schematic illustration of a soil auger assemblyin accordance with one or more embodiments described. In one or moreembodiments, the soil auger assembly includes one or more augers 1,cutting blades 2, handles 3, extension rods 4, working shafts 5, beveledtips 6, and connection rods 7. The auger 1 with cutting blade 2 can bewound spirally on the working shaft 5. The beveled tip 6 is located at afirst end of the working shaft 5. A slotted screw thread 8 can be formedor located at a second end of the working shaft 5.

The extension rod 4 can be integrated with the handle 3. A slotted screwthread 8 can be formed at one end of extension rod 4. At least oneconnection rod 7 can be connected between the extension rod 4 andworking shaft 5. The connection rod 7 can be connected via a slottedscrew threads 8. Slotted screw threads 8 can be formed at the two endsof the connection rod 7 to engage the screw threads 8 of the extensionrod 4 and working shaft 5. Said slotted screw threads 8 can have ahexagonal thickened part 9.

When the soil auger assembly is in use, the extension rod 4 and workingshaft 5 can be connected via the slotted screw threads 8 until theycannot rotate anymore. The hexagonal thickened part 9 can be used tohelp the user connect the components (i.e. the extension rod 4 andworking shaft 5). The handle 3 can be rotated to use the soil augerassembly. The beveled tip 6 is adapted to penetrate the soil as theauger 1 is rotated. The auger 1 loosens the soil and conveys the soilupwards. For large depths, it is possible to insert auger 1 into thesoil and then connect one or more connection rods 7 from the surfacewithout removing the entire soil auger assembly from the hole. Afteruse, the drill can be disassembled and stored separately. This is veryconvenient.
